未替换前hadoop上操作会出现如下警告：
This script is Deprecated. Instead use stop-dfs.sh and stop-yarn.sh 18/01/02 03:01:03 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
解决：
1、下载编译好的native包，解压。
native包：https://files.cnblogs.com/files/yin1361866686/native-2.5.0.tar.gz
2、替换掉/hadoop/lin/native.
3、通过bin/hadoop checknative检验是否成功.
